In the first case, the electric motor test bench is used to obtain the characteristic curves of electric motor under test in order to select proper electric motor during the design phase of an electrified vehicle and building-up a vehicle with desired performance, taking also into account costs, dimensions and other physical characteristics, while in the second case the electric motor test bench is used to obtain maps of the electric motor under test in order to verify the electric motor’s behavior on the base of the modifications done.In this thesis activities, the goal is to build-up a test bench for testing electric motors using a Vehicle Management Unit (VMU), like the one used in vehicles for taking actions on the base of data coming from sensors and for managing these data
